Amazon SDE-DevOps /
Google SRE /
Uber Infra /
Razorpay SRE /
Zomato Platform /
Your resume says: Docker, Kubernetes, Jenkins.
Cool.
But if an interviewer asks any of these into a system design round, can you talk calmly about what you’d do and why?
Beginner:
- Liveness vs readiness vs startup probe
- Health checks causing restart loops
- CrashLoopBackOff and ImagePullBackOff
- One-node cluster as a single point of failure
- Logs eating 100% disk
- Misconfigured resource requests/limits
- Pods never getting scheduled
- Simple blue/green deployment
- Basic alerts on CPU/memory
Intermediate:
- Ingress vs service type LoadBalancer
- HPA scaling wrongly on metrics
- Noisy neighbor on shared nodes
- Central logging with ELK/Loki
- Rate limiting at API gateway/NGINX
- Handling partial outage of a node pool
- Secure secrets handling in CI/CD
- Canary deployment with fast rollback
- Rolling updates vs recreate in K8s
Advanced (where SRE money starts):
- Multi-AZ Kubernetes design
- Zero-downtime control plane upgrades
- Multi-tenant isolation and quotas
- Capacity planning for big sale events
- Incident response and runbooks
- Disaster recovery and backup restore
- Infra-as-code rollback with Terraform
- Debugging random node / CNI issues
- Cloud cost optimization for clusters
Most freshers prepare for:
- “Explain Docker architecture.”
- “Explain Kubernetes components.”
- “What is a pipeline?”
Those are entry ticket questions.
Real interviews go after the tiny production issues that silently break everything.
Being the youngest in the room is the greatest leverage.
You have nothing to defend. So you ask the dumb question, get it wrong fast, and learn what took everyone else years.
@jointhefoundery has been my steepest curve of 2026. Observing KB, @RonnieScrewvala, @nikhilkamathcio & @desaisantosh up close has rewired how I think.
